Title: Photo-sensing device
Inventor: TONAI ICHIRO
IPC: H01L31/105
Filed: 1991-08-30
Granted: 1999-02-02
Abstract: A low doped semiconductive layer is formed an a semiconductor substrate of a highly doped first conductivity type, and first region of a highly doped second conductivity type is selectively formed at a portion of the semiconductive layer.  In a top-incidence type photo-sensing device having a pn junction area of the above structure as a photo-sensing region, the first region is surrounded by a second region of the second conductivity type formed at a portion of the semiconductor layer.  The second region has the same or larger depth as or than that of the first region.  Thus, even if a light is directed to the outside of the photo-sensing region, extra charges generated therein are absorbed by the second region and the flow of the extra charges into the photo-sensing region is prevented.

Title: System for orienting documents in the automated processing of bulk mail and the like
Inventor: HAYDUCHOK GEORGE L
IPC: B07C1/06
Filed: 1992-09-02
Granted: 2003-11-11
Abstract: A series of documents to be processed are optically inspected, and compared with a reference standard to identify the relative orientation of each document. To this end, an image acquired from the document (preferably from each side of the document) is focused on an array of picture elements (pixels) for electronically converting the acquired image to digital form. This produces a digitally encoded image, which can be enhanced if desired, defined by an array of pixels corresponding to the acquired image. For each acquired image, two reference areas, which are preferably symmetrically located on the document, are inspected for the presence of a pre-selected reference mark. Location of the reference mark in one of the two reference areas operates to determine the orientation of the document. Upon locating the reference mark on the document, identifying the orientation of the document relative to the apparatus, the document may then be mechanically re-oriented so that the documents are placed in a uniform orientation for further processing, if desired.

Abstract: A water distillation apparatus includes a cylindrical housing with a first cover thereon, a pair of spaced apart funnel-shaped partitions, a second cover on the uppermost partition and a skirt extending downwardly from the periphery of the cover and the uppermost partition to a location above the bottom of the housing, the partitions and skirt dividing the interior of the housing into an inlet reservoir chamber for cold water above the first partition, a lower boiling chamber beneath the second partition and an inclined condensation passage between the partitions.  Cold water is introduced through a pipe and solenoid valve into the bottom of the reservoir chamber for overflow through an opening in the second cover into the boiling chamber.  A heater in the boiling chamber heats the water to produce steam which rises, passing into the condensation passage and flowing downwardly to a central drain for discharge into a distilled water reservoir beneath the housing.  An overflow pipe connects the top of the casing to the drain so that during filling of the inlet reservoir chamber, the bulk of the water overflows from the reservoir chamber to the drain to flush deposits from the housing.

Inventor: HART ARTHUR CLIFFORD JR
IPC: G02B6/00
Filed: 1993-06-18
Granted: 1998-09-15
Abstract: The presence of (typically unintended) birefringence in single mode optical fiber can severely limit the usefulness of the fiber for, e.g., high bit rate or analog optical fiber communication systems, due to the resulting polarization mode dispersion (PMD). It has now been discovered that PMD can be substantially reduced if, during drawing of the fiber (13), a torque is applied to the fiber such that a "spin" is impressed on the fiber. Desirably the torque is applied such that the spin impressed on the fiber does not have constant spatial frequency, e.g., has alternately clockwise and counterclockwise helicity. At least a portion of optical fiber according to the invention has a spin whose spatial frequency exceeds 4 spins/meter.
